CHARLES HARRISON, OF ARMSTRONG, ILLINOIS.

BARN-DOOR LATCH.

To all whom it may concern:

Be it known that I, CHARLES HARRISON, a citizen of the United States,residing at Armstrong, in the county of Vermilion, State of Illinois,have invented certain new and useful Improvements in Barn-Door Latches;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention has relation to a latching device for barn or other heavydoors.

It is the object of the invention to provide a strong latch forbarn-doors that will endure severe strains and hard pulls withoutaffecting its efficiency, and that may be conveniently operated from theinside or outside to open it-the latching being automatic and that maybe securely protected by a casing on the inside of the door where it issecured.

The nature of the invention is ascertainable from the device portrayedin the annexed drawings, forming a part of this specification, in viewof which it will first be de-. scribed in detail with respect to itsconstruction and mode of operation and then be particularly pointed outin the subjoined claim.

Of the said drawings-Figure 1 is an inside view showing the latch asapplied to a door. Fig. 2 is an outside view of the door at the pointwhere the latch is applied. Fig. 3 is a horizontal section taken in theplane 3-3 ofFig. 1. Fig. 4 is an inside view of the latch removed fromthe door. Fig. 5 is a perspective view of the striker plate and catch.Fig. 6 is a view of the bolt on the door when opened back, and the backcatch about to be engaged by the hook of the outside pull to hold thedoor back.

Similar characters of reference designate similar parts or features, asthe case may be, wherever they occur.

In the drawings, 10 designates the bevel ended latch bolt that isdisposed in a casing 11 forming an open ended square channel having twooppositely disposed outwardly flared securing flanges 12 extendinglaterally from its inner edges, which flanges are perforated for thereception of the shanks of screws by which the casing may be secured tothe inside of a barn-door. This casing is open at its forward end asshown in Fig. 5,

the rear end being closed by means of a perforated stop plate 9 having acentral opening and held transversely within one end of said channel.The forward projected end is square in cross section and beveled as at13 from the inside outwardly so that when the door is closed the saidbeveled projecting end may come into contact with the inclined side ofthe recessed striker-plate 15 and sliding thereon, be pushed back in itschannel and to the opposing stationary part of the door structure. Thehead 10 is of a size to snugly fit into said casing as shown in Fig. 3.The bolt 10 has a square face 7 opposite its bevel end 13, and centrallyprojected from this. face is the straight stem 17 of the pull hook 19,the stem of which extends through the openings within the stop plate 9,the pull hook ending in a recurved portion as shown in Fig. 3. By meansof this pull hook 19 the bolt 10 is secured to the housing. Thishousing, as shown in Fig. 4, is entirely open upon its under side, andthe door to which the latch is secured forms the fourth side of the boltchannel. Held upon this stem 17 and interposed between the stop plate 9and the end of the bolt 10 is the spring 18, which normally forces thisbolt outward. From the inside the, bolt is operated by means of thispull hook 19. The bolt is operated in opening the door against thestrain of the spring 18. 20 designates a laterally extending pull hookwhich is projected through the open bottom of said casing and is adaptedto extend through a slot in the barn-door and is connected at its innerend with the rear face of the bolt 10 so that from the outside the doormay be opened by pulling back on the pull-hook 20. In this way a veryefficient and at the same time a simply constructed and readily operatedlatch is provided for a barn-door that may be operated either from theoutside or from the inside. From this it will be seen that the casing 11forms a bolt receiving channel within which the bolt is snugly held. Thehook 20 is so constructed that when the door is opened back fullyagainst the adjacent side of the barn A it may engage a catch 21suitably secured thereon to hold the door open, and against being blownshut by the wind as indicated in Fig. 6, where the door is representedas just approaching its full-open position. It is that the pull 20 mayperform this function as well as being convenient to catch hold of thatit is given a, hook-like form. This construction provides a strong,simply constructed barn-door latch which can be operated from bothsides.

As disclosed in Fig. 6 the outside pull hook 20 is made to serve adouble purpose, in that in providing an ordinary staple and securing thesame at the proper point, the barn-door may be held in an opencondition, in that the hook 20 will engage the staple and so prevent anyslamming of the door or accidental closing of the same during aWindstorm.

The securing flanges 12 extend the full length of the channel formingbottomless housing, and the bolt 10, it will be noted, is of a lengthless than said channel. The hook end of the member 19 is normally inengagement with the end of the casing 11 as shown in Fig. 4 and limitsthe outward movement of the bolt 10. This pull hook 19 thus performs atriple function in that it serves as a pull for the bolt, prevents thebolt from becoming detached from the housing after the latch has beenassembled and finally serves as a stop in limiting the outward movementof the bolt 10.

Having thus described the invention, what is claimed as new, is z- Thecombination with a latch housing bent to form a top and two sides, saidhousing having a uniform rectangular interior cross section throughoutits length, each of said sides having a perforated securing flange, astop plate having a central opening closing one end of said housing; arectangular latch bolt within and closing the other end of said housing,a pull hook pass ing through and completely filling said central openingand being secured to said latch bolt,.a spring held entirely Within theeasing and coiled about said hook between said latch bolt and stopplate, the end of said hook being normally held in front of said top,and a laterally extending pull hook projecting from said latch boltbeyond said bottomless housing in a direction at right angles to saidfirst mentioned pull hook, all arranged as set forth.

@111 testimony whereof, I afliX my signa ture, in presence of twowitnesses.

CHARLES HARRISON.
